Resistance thermometers

Resistance thermometers with Pt100/Pt1000 resistance

Resistance thermometers are equipped with platinum sensor elements which change their electrical resistance as a function of temperature. In our range of products you will find resistance thermometers with connected cable as well as versions with connection head. A temperature transmitter can be installed directly in the connection head. Resistance thermometers are suitable for applications between -200 ... +600 °C (dependent on instrument model, sensor element, accuracy class and materials coming into contact with the medium). Accuracy classes AA, A and B apply to all resistance thermometers. They are available with a tolerance value to IEC 60751.

FAQ

The standard WIKA measuring insert allows use up to 3g (amplitude). This corresponds to a loading of 6g, peak to peak, per DIN EN 60751 (58.86 m/s^2). In EN 60751 only 20-30 m/s^2 peak-to-peak is specified (1 g = 9.81 m/s^2). The vibration-resistant design is suita ... More

What are the Callendar-van-Dusen-coefficients and how do I calculate these?

The Callendar-van-Dusen-coefficients are used to describe a polynomial function of the actual characteristic of a platinum measuring resistor. This can be stored in a transmitter and thus increases the accuracy of the entire measuring chain. To calculate the Callen ... More
